PERFORMANCE EVALUATION OF PRM-BASED AVAILABLE BANDWIDTH USING ESTIMATION TOOLS IN A HIGH-SPEED NETWORK ENVIRONMENT

Abstract

Awareness regarding available bandwidth value between two terminal devices is applicable for solving a wide variety of networking issues. This value causes challenges for an accurate network monitoring and optimization of link capacity usage. Among the various metrics that belong to the traffic monitoring on a network path, this research is focused on available bandwidth estimation. The methodology of probe rate model for the available bandwidth estimation in wired networks is considered. Characteristics of the existent tools – Kite and Yaz are given and the prototype of a new developed tool Kite 2 is described. A comparison of tools for available bandwidth estimation performance in the high-speed environment is given.The optimized configuration of each tool in comparison to its default settings is proposed.
